Check the "I have read and accept..." box, optionally actually reading the TOS.

Uncheck the "mail me unless you want to get news about TalkShoe.

The next page will ask for a PIN. While they recommend using your phone
number as it will be easy to remember, you can chose ANY 10 digit number.
If it is taken, you'll need to try another number. This number will be your
unique id, so there's no getting around it.

Calling in during the show

Each TalkCast has a unique identifier. To listen, chat on or participate in any Cast, you will need to call the TalkShoe telephone number. You will be asked for the show id and your id. Each of these numbers is ended by the # key, not unlike calling your bank's vocal server. For example, WineLoversPage.com TalkShoe ID is 11888, so after calling the number, as soon as you hear the auto message begin, enter

11888#

Then the voice will request you enter your 10 digit PIN (yes it's a pain, I know)
so if this were 1234567890 you would enter

1234567890# (this should be your PIN)

That's all there is to it! (Irony)

Actually, it's not all there is to it if you want to use the text chat or
listen while watching the text chat. To do this you'll need to download a program that
allows you to do these things.
Try it, you may like it, there's nothing dangerous here, but if it doesn't work for you,
let it go, you can still listen live or to the recorded versions.
